When you get your machine all set up and press the BSR 1, did the red light come on under the BSR foot?(I can't get used to BSR 2) If the light doesn't come on, it is not working. The BSR is made to work when it reads the fabric moving under it. I set mine on a medium speed and find that I still need to use my FMQ skills to get a good consistant stitch. Mine does prevent the micro stitches I used to get with FMQ which was what I wanted. I still get the occasional bigger stitch which I fix by hand. It might also be helpful if the bell is engaged on your machine for a while that tells you when you are not moving the fabric so it can read it. My dealer turned mine off for me because I find it too distracting.
With all that being said, I find it more difficult to try to follow a stitching pattern or applique shape rather than FMQ stipple or meandering.
